I thought about this purchase for a long time, as I understand that headphones of this type may not be suitable. I decided to buy it anyway and . I canβt give a definite answer yet. On the one hand, the headphones are good because they sit like cast, do not fall out, do not stick out and look quite good, neat. The sound is quite acceptable, it sounds crystal and loud, classical music and vocals sound especially good, but they regretted the bass, there are not enough low frequencies. Noise suppression system I can not understand yet. It seems to muffle something, but it does not completely cut off extraneous noise. A huge plus, of course, is the ability to talk without taking them out. By the way, this function works on certain words (I think I figured out the developers)) It is enough to say "hello" quietly and the microphones immediately turn on, and the music is muted. Basically satisfied with the purchase. I will add a review later.
